1,079,511, Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JAooB J. PLUCKER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia rangements of parts as Will be more fully hereinafter described and pointedout in the claims.

Inthe accompanying drawings: Figure 1 and State of. Pennsylvania, have invented is a brokenviewin longitudinal section illuscertain new and useful Improvements 1 n trat ng my improvements in connection: with Heaters, of which the following is a spec1- asectional hot Waterheater. Fig.2isaview in fication.

My invention relates to improvements in heaters, the object of the invention being to provide sectional heaters, either steam, hot water, or hot air with integral-air heating passages through which air from the outside is compelled topass-in a long circuitous elevat'ion'of one of'the sections showing the same at right angles to the position shown in Fig. 1. Fig. 3 is a view in vertical section on an enlarged scale on the line 33 of Fig. 2. Fig. at is a view in horizontal section on an Fig, 5 is a view in horizontal section on an path and be superheated before discharging enlarged scale on the line 5-5 of Fig. 2. into the combustlon chamber in close prox- Fig. 6 is a view in section on the line 6-6 imity to the fire, so as to consume the otherof Fig. Fig. 7 isa view in horizontal Wise waste products of combustion. Y

A further object is to provide improvements of this character which form a portion of the furnace as distinguished from an attachment and in. assembling the furnace asmany of such sections may be utilized as desired.

A further object is to provide a sectional furnace in which several of the sections are formed with integral air superheating passages or. chambers with air inlets. communicating with the outside, and. caps for said inlets to reduce the flow of air.

Heretofore various attachments have been devised for heaters with a view to admitting hot air into the combustion chamber. Such attachments are secured to the furnace in various Ways, but due to the heat of the furnace are quickly disabled and are of service but a comparatively short time.

It is the purpose of my invention to pro vide a furnace section which will have an integral air heating chamber or passage which is a permanent integral part of the section, and not an attachment for the furnace, By reason of this arrangement, the air heater may be cast of the same metal as the sections and of any desired thickness, so that it will be able to Withstand the heat of the fire as long as the furnace lasts. My invention is therefore not anrattachment but for a permanent part of the heater structure.

WVith these and other objects in. View, the invention consists in certain novel. features of construction and combinations and-arsection illustrating my improvementsin cona fragmentary view 8-8 of'Fig. 7. r I

While my improvements are adapted for use inconnection with any style of sectional heater, either for steam, hot water, or hot. air,,I have illustrated the same in Figs. 1 to 6 inclusive in connection with a sectional hot water heater, and in Fig. 7 in connec tion With a circular Water heater of the sectional type. Referring to Figs. 1 to 6 inclusive, 1 represents the sections of the heater, and as many of these sections may be secured together as desired. Each section comprises a single integral casting made hollow throughout its upper portion 2, and has legs 3 with a hollow connecting partition 5, so that passages 6 are formed for the passage of. smoke and gases. Thisparticularstyleof section-is not material, as my invention may be used on any style of sectioinbut is shown in connection With this style for purposes, of illustration only.

My improved air heating chambers 7 are cast integral- With certain of the sections 1, and are preferably spaced fromthe sections by integral blocks. 8, sothat the smoke and. gases are free to pass all around the air. chambers and against practically the entire surface of the section. to. heat the Water. These air chambers 7 in vertical longitudi nal dimension are angular in shape, and in transverse horizontal section are oblong in shape.

in section on the line enlarged scale on the line H of Fig. 2.

nection with a, circular heater, and Fig. 8 is i bridge 4: and hollow i the outside air, and projectsslightly beyond For clearness of description, I have given the vertical portion of the chamber reference numeral 9 and the horizontal portion 10, but it is to be understood that these are continuous chambers and are divided by a plurality of partitions 11 integral with the walls of the chamber and forming a con tinuous circuitous passage throughout the chamber. In other words, certain of the partitions 11 extend from the lower end of the chamber to a point short of the end of the horizontal portion 10, while others terminate short of the lower end of the chamber, and extend entirely to the end of the horizontal portion 10. v

While I have illustratedbut'thre'e partitions, it is of course to be understood that thenumber is not limited, as "I may form the passage of any desired length.

An integral entrance tube 12 connects the lower end of the chamber 9 at one. side with and at its ends is spaced apart, because they terminate adjacent the furnace door 18.

19 is the air inlet to this chamber 17, and air is admitted to one end of the chamber, and through the medium of the partitions 20, corresponding to partitions 11, the air is compelled to move in a circuitous path throughout the curved chamber 17. The last run of the chamber 17 is provided with perforations 21, so that the superheated air will commingle with the smoke and gases and perfect combustion as in the preferred form. Itis to be understood that this chamber 17 is integral with the furnace section, being preferably connected therewith by integral blocks 22 so as to allow a space between the chamber 17 and the wall of the heater for the smoke and gases.

Various other slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but conthe outer face of the furnace section in position to receive a cap 13 to close or partially sider myself at liberty to make such changes close the entrance. .This cap is designed and alterations as fairly fall within the primarily for use at night when the fire is spirit and scope of the appended claims.

by a chain 14: to prevent loss of the cap.

The run of the passage in chamber 7 farthest removed from the entrance 12 is pro- 1 claim as new and desire to secure by Letters Patent is:

1. A heater comprising a longitudinal series of inverted U-shaped furnace sections, certain of said sections having L-shaped air chambers cast integral with the sections, spaced from the inner walls of the sections and having their horizontal portions located near the tops of the sections, said air chambers having outlets for discharging hot air into the inside of the sections, and having inlets communicating with the outside of the sections, substantially as described.

2. A heater comprising a plurality of sections secured together, certain of said sections having at opposite sides independent air heating chambers, said chambers integral with the section located entirely within the section, having outlets discharging into the inside of the section and inlets communicating with the chambers of L-shaped form having vertical and horizontal portions, and partitions within the chambers compelling a circuitous passage of air therethrough, substantiallyas described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JACOB J. PLUCKER.

I be arranged in. any desired way to allow the a1r to escape, and

fire. It will be seen that the cold air from the circulate in a long circuitous passage through the chamber 7, and in such passage will become highly heated by the heat radiation fro-1n the walls of said chamber, and finds exit through the perforations 15, it will perfect combustion to a material extent, so that smoke and gases which would otherwise be lost, will be consumed.

As above stated, the chambers 7 are cast They are notseparate attachments, but are formed in the same mold with the sections, and are parts of thesections, and are therefore of the same cast iron and able to withstand the heat to which they are necessarily subjected. f In Figs. 7 and 8, I have illustrated my improvementsin connection with a circular heater 16. This circular heater 16 is to be .made in sections as all ordinary heaters are to be made, and is provided with an integral air heating chamber 17. This air heating Witnesses: chamber 17 corresponds to the chamber 7 G. R. ZIEGLER, with the exception that it is curved in form, S. ,VV. FOSTER.
